A new camera is improving the efficiency of the Near-Earth Asteroid Program at the Center for Solar System Studies. This update from Shoemaker NEO Grant winner Bob Stephens reveals amazing recent progress using his 2013 Planetary Society grant.
What a huge relief: there is finally a place for New Horizons to visit beyond Pluto. A team of researchers led by John Spencer has discovered three possible targets, all in the Cold Classical part of the Kuiper belt. One is particularly easy to reach. New Horizons would fly past the 30-45-kilometer object in January 2019.
What's that in the distance? A binary star? Those are two little round worlds dancing in circles, whirling around a point in space located between the two of them. It's Pluto and Charon, clearly separated by New Horizons' camera.
Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.
An attempt to corral the discussion of the IAU planet definition in one place on planetary.org, so that we may be free to actually discuss Kuiper belt observations and scientific results on posts elsewhere on this site.
On the heels of last weeks reports of a second Sedna and a ringed Centaur comes a third cool outer solar system discovery: A new, likely large member of the Kuiper belt. With an absolute magnitude of about 3.0, the new object currently known as 2013 FY27 is the tenth brightest object beyond Neptune .
On Wednesday, March 26, two important discoveries in the outer solar system were announced: the discovery of the second confirmed member of the Inner Oort Cloud (2012 VP113) and the discovery of rings around the planetesimal Chariklo. In a Hangout on Air, a rag-tag group of planetary scientists and astronomers active on Twitter talked about the discoveries.
